Advances in Speech Production: Tools, Techniques and Recent ResearchDescriptionThe process of orally communicating our thoughts, intentions, feelings and attitudes requires speech production. This process is complex and occurs through coordination of respiration, phonation, articulation and resonance. Articulation constrains speech acoustics via continually varying configurations of the human vocal tract and the position of the speech articulators (tongue, lips, jaw, velum, and larynx). Recently, tools for examining speech production have been developed that, for one thing, allow for a better understanding of the relationship between speech articulation and acoustics. Such tools permit the collection of basic data that can contribute both to theory (speech production models) and practice (describing variation in normal and pathological production). The ARC Human Communication Sciences Network (HCSNet) is holding a workshop to introduce and describe the function of some of the tools used in speech production research, e.g., EMA, NDI WAVE system; Optical motion capture, Ultrasound, Electropalatograph (EPG), Electroglottograph (EGG). This workshop will provide hands on demonstrations of how such technology is being used to explore the intricacies of both speech production and perception. The meeting will include keynote addresses by international and national leaders in the field, including: ERIC VATIKIOTIS-BATESON, U British Columbia (Canada), Linguistics Department and Cognitive Systems Program AudienceThis event is aimed toward higher degree research students, postdoctoral fellows, and established researchers in speech sciences, phonetics and psycholinguistics whose research includes study speech production, and/or who want to incorporate into their research toolbox one or more of these cutting edge technologies for investigating the multi-faceted and multi-modal dynamics of human speech. Event FormatMARCS Auditory Labs provide the perfect venue since all of the equipment is on site. Furthermore this two day workshop will provide a tangible spur for sets of national and international collaborations. Brief overview of the demonstrations/workshop 2. EMA + Vicon system. A more traditional solution to tongue tracking, with the innovation of simultaneous 3D face motion tracking 3. 2D/3D motion tracking and 4dMd scanner, for speaking face studies. In addition, two research systems that provide high quality video tracking will be demonstrated with hands-on practice 4. Ultrasound for speech research. The relatively new application of ultrasound to speech production research provides data on the dynamically changing shape of the surface of the tongue blade and body as a whole during speech. 5. Electropalatagraph. This technique provides relatively fine-grained time varying information about contact between areas of the tongue's surface and the hard palate (roof of the mouth) during speech. 6. Electroglottograph. This device measures the activity of the glottis during speech, providing information about the timing and rate of glottal pulsing (opening-closing cycles of the vocal folds), or voicing, during speech. 7. Motion-capture visualization. FaceRobot & Matlab GUIs 8. Data Analysis (PCA, ICA, FDA). Important Dates
